About Warren Township High School District 121
Warren Township High School District 121 operates one high school across two grade-based campuses. O’Plaine generally serves grades 9–10 and Almond grades 11–12, so students normally change buildings after sophomore year while remaining enrolled in Warren Township High School.
Separate registrars, bell schedules, and daily operations reflect the different grade bands, while transcripts, graduation requirements, and the school identity remain unified. Residence establishes eligibility for District 121; the standard four-year campus sequence is then determined by grade.
Bridges includes evening and transition programming entered through referral, a Success meeting, and an individualized Student Success Plan. Eligible transition students work on employment, independent living, and community access, usually through age 22. The ordinary student movement is O’Plaine followed by Almond, with Bridges providing individualized arrangements alongside that shared progression.
